General description

Standard cable ducts are prefabricated reinforced concrete ducts that, due to their structure, can be built extremely efficiently, and are easy and fast to install. These cable ducts are primarily designed for connection to plastic cable ducts, but can also be used for a range of other purposes.
All of B+F’s cable ducts have the same special shape – i.e. a conical taper towards the front – and differ only with respect to their structure. B+F’s standard 75 K1 cable duct consists of two elements, which are roughly the same size (top and bottom). This type of duct can be built and installed extremely efficiently. They are suited for use in areas where there are no existing cables that need to be taken into consideration when installing it.

B+F’s standard 75 K2 cable duct, whose bottom parts are divided into two parts across their length, are suited for use in areas with existing cables or third-party equipment that need to be taken into consideration when installing it, or that do not permit the installation of a fully closed duct.

B+F’s standard 75 L2 cable duct, which is divided into two parts both across its length and crosswise, offers the same flexibility with regard to installation as 75 K2. These ducts are also suitable for use in pits that need to be reinforced with struts during installation.
